I just renovated a desktop that had been in storage for a while and I am looking for good ideas for data analysis or numerical analysis projects in physics. I have taken up to E&M, and special relativity, (including mechanics) in college, so I know a bit, but not that much.
Also, what are good software packages to play around with? And, tutorials?
Edit to make the question more specific: Is there open source astrophysics software? For like, simulating galaxies and such? I know there are games like on steam where you can visualize toy galaxies, but I'm looking for something more substantive.
Alternatively, simulation tools for: electromagnetism; magnetism/magnetic materials (would be really cool to get into, as I've only been teased by this subject in the past, like histeresis and the different kinds of magnetism--and an electric field going at the speed of light is a magnetic field in a stationary reference frame!); traffic science; materials science solely; acoustics; optics/lenses; ocean science, waves and tides and such; atmospheric science; particle physics?
I've been curious about a lot of things for a while, and my life has recently mellowed out enough to give me time to get into it... sorry if that comment wasn't entirely relevant...
